Abstract

Optical fibre sensors have been extensively employed as real-time damage detection tools in advanced aircraft and space vehicles. However, the practical applications of this kind of sensors to real civil engineering structures have not been widely adopted. A structural health monitoring system - Wind and Structural Health Monitoring System (WASHMS) for the Tsing Ma Bridge has been operated since the bridge commissioning in May 1997. This paper presents a study using fiber Bragg grating sensors to measure strain responses of the Tsing Ma Bridge and compare the results with those obtained from W ASHMS using traditional resistive strain gauges. The measurement results using FBG sensors were in excellent agreement with those acquired by WASHMS.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
